Step-by-step explanation:
make a 4 square box. put the numbers 10 & 2 on top an 8 & 10 on the side.then multiply...
8 * 10 = 80
8 * 2 = 16
10 * 10 = 100
&
10 * 2 = 20
then add all the numbers together.... 80+16+100+20 = 216 meters
the end. Can u mark me the brainliest when u get the chance? thnxs
Answer:
Step-by-step explanation:
- Diagonals of a rhombus are perpendicular.
- Sides are of equal length.
<u>Use Pythagorean to work out the side length.</u>
- a² = (d₁/2)² + (d₂/2)²
- a² = (24/2)² + (45/2)² = 650.25
- a = √650.25
- a = 25.5 cm
<u>The perimeter is:</u>
- P = 4a
- P = 4*25.5 = 102 cm
Answer:
3 feet
Step-by-step explanation:
half his height
Answer:
x = 2
Step-by-step explanation:
9^2 or 9(9) = 81
<u>Define x:</u>
Let one of the numbers be x.
The other number is x + 2
<u>Construct equation:</u>
<span>twice the smaller is 16 more than the larger
</span>⇒2x = x + 2 - 16
<u>Solve x:</u>
2x = x + 2 - 16
x = -14
<u>Find the two numbers:</u>
Smaller number = x = -14
Larger number = x + 2 = -12
Answer: The two numbers are -14 and -12
